Objective: The aim of this study was to determine the reliability and validity of the Turkish version of the Two Track Model of Bereavement Questionnaire (TTBQ-T) (Rubin et al. 2009), a-70 items questionnaire for comprehensively evaluating the process of bereavement.
Materials and methods: The questionnaire was initially translated from English into Turkish, and then back translated. Subsequently, it was administered to 205 bereaved individuals that lost a significant other within the last 5 years. In order to assess the questionnaire's validity, the Beck Depression Inventory (BDI) and the Impact of Event Scale-Revised (IES-R) were also administered to the participants. The factor structure, total reliability, and test-retest reliability of the TTBQ-T were evaluated.
Results: Factor analysis yielded results that were, for the most part, similar with those yielded by the original study; however, there were some cross loading items that yielded a 5-factor solution (Relational active grieving, Close and positive Relationship with the Deceased, Traumatic perception of the loss, Conflictual relationship with the deceased and Social Dysfunction). Cronbach's Alpha coefficients for these 5 factors were 0,91, 0,88, 0,82, 0,78 and 0,65 respectively. In order to determine if the responses were loaded under 2 tracks, a higher order factor analysis was conducted. The relationships between BDI and IES-R, and TTBQ-T total scores were examined in order to determine the construct validity of the TTBQ-T. The present findings indicate that TTBQ-T has construct validity.
Conclusions: The findings indicate that TTBQ-T is a reliable and valid the questionnaire for use in Turkey. The findings are discussed in the light of the literature.
